Ikelite EV Controller

This is a NEW EV (exposure value) Ikelite Controller. I am simply not "pro" enough to make use of it as a more serious photographer would be. Brand new price is $150.00. Here is the description from the Ikelite homepage EV ControllerProvides 10 manual power settings in half-stop increments for SubStrobe DS-50, DS-51, DS-80, DS-125, DS-160 and DS-200 models. Any of our sync cords can be attached to the bulkhead on the EV Manual Controller; or the Controller also has a sensitive slave sensor allowing it to be triggered by another strobe. Simply point the Controller at a camera housing for dependable strobe triggering by the camera strobe without requiring fibre optic "sync cord" nonsense of other strobe systems. The Controller attaches to the strobe and mounts near the housing, providing maximum versatility and control of flash exposure. It can be used with normal or pre-flash camera and strobe systems. A second strobe with a Manual Controller can be set to any desired power and will operate dependably with the built-in slave sensor of the Controller aimed at the subject or the primary strobe; or the Controller can be connected to a dual sync cord.
